Error after changeset for - Replaced 'PdfSharp' with 'iTextSharp'

After applying changeset
3ffc5ce5f32d
Replaced 'PdfSharp' with 'iTextSharp' (custom version with AllowPartiallyTrustedCallers attribute).

Error
Could not load file or assembly 'MigraDoc.DocumentObjectModel

Also, I don't see that an iTextSharp pakage folder was created

Try to clean the solution (Right-click on your solution, click 'Clean solution').

iTextSharp is stored in \packages\nopCommerceCustom directory

I had to delete file MigraDoc.RtfRendering.dll from  \src\Presentation\Nop.Web\bin
